I have php pages that let me view, add, delete records in database, but I can't make it work to edit record. I have problem to get id to edit_h.php. When i enter id number manually in ("UPDATE uzytkownik SET LOGIN = :login WHERE id = :id") it works fine. I am stuck with this problem for a bit now. Thanks for any help in advice.
Here's my code:
edit.php
<?php
session_start();
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Edytowanie uzytkownikow</title>
</head>
<body>
<form action="edit_h.php" method="post">
Login:<br>
<input type="text" name="login">
<br>
<input type="submit" value="Edytuj">
</form>
</body>
</html>
edit_h.php
<?php
include_once "polacz.php";
$id = $_GET['id'];
$login = $_POST['login'];
$con = polacz();
$stid = oci_parse($con, "UPDATE uzytkownik SET LOGIN = :login WHERE id = :id");
oci_bind_by_name($stid,':login',$login);
oci_bind_by_name($stid,':id',$id);
if (oci_execute($stid))
{
header("Location: view.php");
}
else
{
echo "blad";
}
view.php
<?php
include_once "polacz.php";
session_start();
if (!isset($_SESSION['id']))
{
header("Location: login.php");
die();
}
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Logowanie</title>
<style>
table {
border-collapse: collapse;
width: 100%;
}
th, td {
text-align: left;
padding: 8px;
}
tr:nth-child(even){background-color: #f2f2f2}
th {
background-color: #af504c;
color: white;
}
</style>
</head>
<body>
<?php
echo "Witaj ".$_SESSION['login'];
echo '<br><a href="logout.php">WYLOGUJ SIĘ</a><br>';
$con = polacz();
if (isset($_GET['sort']))
{
$sort = (int)$_GET['sort'];
if ($sort == 1)
{
$sort = 2;
}
else
{
$sort = 1;
}
}
else
{
$sort = 1;
}
$dbsort =array(1=>'ASC',2=>'DESC');
$stid = oci_parse($con,"SELECT id, login FROM uzytkownik ORDER BY login ".$dbsort[$sort]);
oci_execute($stid);
echo "<table>";
echo "<tr><th>ID</th><th><a href=\"view.php?sort=$sort\">Login<th>Usun</th><th>Edytuj</th>
</th></tr>";
while (($row = oci_fetch_array($stid, OCI_ASSOC)) != false)
{
$id = $row['ID'];
$login = $row['LOGIN'];
echo "<tr><td>$id</a></td><td>$login</td>
<td><a href=\"delete.php?id=$id\">Usun</a>
<td><a href=\"edit.php?id=$id\">Edytuj</a></tr>";
}
echo "</table>";
echo '<br><a href="add.php">Dodaj uzytkownika</a><br>';
?>
</body>
</html>
